The air-to-ground phone patch is accessible via which interface?

• A. Flight deck interphone
• B. Cabin interphone
• C. Public address system
• D. Satellite link

Answer: (A)

The air-to-ground phone patch is a cockpit-to-ground voice channel and is accessed through the flight deck interphone. This interface is the dedicated control path for external calls from the pilots, allowing direct contact with ground operations. The cabin interphone is used for crew-to-cabin communication, the public address system for passenger announcements, and the satellite link is a separate communication path not used for the standard air-to-ground patch. So the correct interface is the flight deck interphone.
